nnrrnn nnw'nnn To all who/m it may concern:

Be it known that l, EDWARD Ci-nnnns CoL- soN, citizenot the UnitedStates, residing at Chicago, in the county ot Coolr and ,State otIllinois, have invented certain new and useiiul improvements inSteam-Pipe-Joint Connections, of which the following is a specitication.

This invention relates to improvements in steam pipe joint connectionsand is especially designed for use in connection with steam heatedrolls, such as paper calendering rolls, ironing or mandrel rolls andfinishing rolls for linishing cloth.

One of the objects of the invention is the construction of an improvedsteam joint adapted to allow for an irregular movement of the heatingrolls with which it is ber adapted to hold the joint steam tightconnection with the rolls.

Another object ot the invention is to provide a steam pipe joint adaptedfor use in connection with heating rolls with means arranged thereinadapted to hold the joint steam tight under all conditions and to allowfor the vertical and lateral movement of the roll which is connected toit.

W ith the above and other objects in view the invention embraces certaincombinations, constructions and arrangements of parts, clearly describedin the following specilication and clearly illustrated in theaccompanying drawings, in which Figure 1 is a central longitudinalsectional view or" the improved steam joint showing the saine in normalposition, Fig. 2 is an end view thereof, Fig. 3 is a centrallongitudinal sectional view showing the steam joint in the position itwould occupy it the roll to which the joint is attached should settle orbe moved, F ig. 4 is a detail sectional view, on an enlarged scale, of acasing, Fig. 5 is a detail plan view of a gland member, Fig. G is adetail end view of a movable float member adapted to hold the jointsteam tight under all conditions, and F ig. 7 is a detail side elevationof the lioat.

Referring to the. accompanying drawings, which are merely illustrativeof one form of the invention, 1 denotes a hollow steam ironing orpolishing roll, on the outer end of which a casing 2 is suitablyconnected by means of screws or other fastening means, not shown. Thecasing 2 is formed with internally projecting spaced annular flanges orshoulders 3 and et. The flange or shoul- Speccaton of Letters atent.

der 3 is formed with a beveled inner surface while the flange is termedwith a surface adapted to occupy a position normally parall el with theaxis ot the roll 1.

A. float member 5 projects into the bore ot' the roll 1, said memberbeing formed with a rounded enlarged head t5, engaging with an annularor tubular projection 7 on the inner end of the casing` 2, which tubi.-lar projection surrounds the rounded head 6 and is formed with inclinedports S, spaced apart thereon. rEhe outer end ot the float member 5 istermed with a head 9, very much larger than the head (i, and said head 9is adapted to engage with a holding gland 1,0, which is secured by meansoipv screws 11 to the casing 2. The head 9 is formed with a convex outersurface and the gland 10 is formed with a concave inner surface, wherebythe head can have close movement against said gland and be in positivecontact with the same at all times. The gland 10 is formed with anopening 12, which has an inclined wall, and is provided with balls 13,located in a ball race 1i, having a hardened bottom washer 1.5 therein.rlhe gland 10 is also termed with laterally extending oil ports 1G,whereby the conv surface of the float head may be lrcpt constantlylubricated, oil being supplied through said openings by means ot an oilcup 17, located on the gland 10.

.it steam inlet pipe 18 is threaded on to the head S ot the float and onits outer end carries a tee litting 19, tlneadcd thereon. vWithin thebore of the pipe 18 an exhaust pipe projects, said pipe passing into thebore oit roll 1 beyond the inner end ot the tubular extension 7, ot thecasing 1. rlhe outer end ot the exhaust pipe Q0 is threaded to the teeiitting 19, which is provided with an ii'iternal partition A cone washer22 normally holds the balls 13 in place in the race 14, and said conewasher is normallyv held against said ball 13 by means ot a spiralspring positioned around the pipe 1S and engaging at its outer end abearing washer i, movable on a nut adjustable on the pipe 1S, which isprovided *ith screw threads tor this purpose. Normally the pipes 1S and2O occupy a position parallel with the a2-:is of the roll 1, but whenthe roll should be moved the float member 5 and the pipes will be forcedto an angular position, the tloat member by contact closely with thegland 10 taires up all looseness which normally might occur. This memberis held in positive engagement with the gland 10 by the pressure of thesteam in the pipe l, which is exerted against the inner side of the head9, of said member 5. No matter to what angle the roll 1 may be moved thejoint will be held steam tight by means of the float member 5. The floatmember1 5 is adapted, with the assistance of the spring 23, to hold thepipes 18 and 20 normally in a center position, in this way the float 5acts as a centering device.

Having described my invention I claim l. In combination, a hollow casingconuectible to a. hollow heating roll, a gland secured to the casing, afloat member movable against the gland and the casing, a steam inletpipe threaded to the float member and a steam exhaust pipe projectingwithin the inlet pipe.

2. In combination, a hollow casing connectible to a hollow heating roll,a gland having a concave inner surface mounted on the casing, a ioatmemberv having a head formed with a convex surface engaging with theconcave surface of the gland, an inlet steam pipe connected to thegland, and an exhaust steam pipe projecting through the bore of theinlet pipe.

3. In combination, a hollow casing having a tubular extensionconnectible to a hollow heating roll, a float member formed with arounded head engaging with said tubular extension, said float memberhaving an enlarged head with a convex surface, a gland secured to thecasing having a concave surface engaging with the convex surface of thefloat member, an inlet pipe threaded to the float member and an exhaustpipe projecting through the bore of said float member.

4. In combination, a hollow casing connectible to a hollow heating roll,a gland secured to the casing, a float member engaging with the gland, asteam inlet pipe connected to the float member, balls located on thegland, a cone washer engaging the balls, a spring engaging the conewasher, an adjusting nut threaded on the inlet pipe engaging the spring,an exhaust pipe within the inlet pipe, and a tee fitting connected tothe outer ends of the pipes having a spacing partit-ion therein.

5. In combination, a hollow casing connectible to a hollow heating roll,a gland secured to the casing, a floating center member secured withinthe gland and casing, an inlet pipe connected to said floating centermember, an exhaust pipe within the inlet pipe, and a fitting having aninternal spacing partition connecting the pipes.

6. In a steam pipe joint connection, a cylinder, a casing provided witha tubular extension secured to one end of the casing wit-h saidextension projecting into the cylinder, a float member having anenlarged inner end bearing with said end within the tubular extension ofthe casing, a threaded inlet pipe secured to the outer end of the float.member, said outer end of the float member being provided with av convexsurface, a gland having a cone shaped opening and a concave inner endsecured on the casing around the inlet pipe with said concave endbearing against the convex surface of the float member, a spring aroundthe inlet pipe bearing against the gland, a divided fitting on the outerend of the inletpipe, and an outlet pipe connected to the fitting eX-tending through the inlet pipe and the float member into the cylinder.

7. In combination with a cylinder, inlet and outlet end pipes for thecylinder, and means adapted to center said pipes relative to saidcylinder holding said pipes in position thereon.

8. In combination with a cylinder, a tubular member extending within oneend of the cylinder, an outlet pipe projecting through the member, meansfor centering said pipe relative to said cylinder and an inlet pipe heldin place by said means.
